What else can I help you with?
Is active is a cutoff region of transistor?
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
What is the biasing technique in transistor for it to be in active region?
For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.
Is transistor a linear or non linear device?
we will operate transistor mainly in 4 regions..namely active ,cutoff,saturation and pinch off region depending on the type of biasing. if it is under active region then transistor is a linear device.. linearity in the sense if the output is proportional to input then it is said to be linear.
What is saturation and active region in a transistor?
The output current of a transistor is controlled by the current in the 'base' input: Increasing the control current will increase the output current in a more or less linear fashion. In the saturation region, this is no longer true: The transistor is nearing the limits of how much current it can conduct, so increasing the control current further has little or no effect. When using a transistor as an amplifier, you want to stay away from the saturation region as it would distort the signal you are amplifying. When using a transistor as an on/off switch, as in digital circuits, being in the saturated region is 'on' and a normal mode of operation.
What is cutoff region in transistor?
The cutoff region is when the transistor doesn't have sufficient base current to drive a larger current from emitter to collector. Therefore, the transistor does not turn on and stays shut off.
